Interesting. Perhaps something like
foreign import "volatile &periphBase" :: Ptr Word32
which will declare
extern volatile uint32_t periphBase in the file, then you would just have a linker symbol periphBase at 0x4000000. (or just import a value with zero and do pointer arithmetic like you do)
Ah. It's nice for Cortex-M3! But I would like to rewrite NetBSD kernel with jhc and Haskell code. http://netbsdman.masterq.net/org_netbsd/src/share/man/man9/bus_space.9.html NetBSD doesn't touch raw memory directly. It has own bus driver. I would like to rewrite the bus driver with jhc. How do I write the code with extern volatile style? Thank's, -- Kiwamu Okabe
